Using Sortable on a table in a chrome browser gives a weird behaviour. Dragging a row around the table makes a gap appear between the top row and the table header. dragging the lowest row outside the table makes a gap between the rows.

i've been looking for a solution all over but none found. is there any here?

thanx,

Thomas

EDIT: further inquiring showed me that it has something to do with chrome behaviour with calculating heights of elements. anyone?
